In early 2020, Micron’s software engineers announced HSE, an open-source storage engine designed for SSDs and persistent memory, a fast key-value storage database. HSE 2.0 debuted last year and no longer relies on modifications to the Linux kernel in favor of a completely user-space-based solution.
This week, Micron released HSE 3.0, an open-source storage engine that brings even more feature improvements.
HSE 3.0 is described as having improved data management and enhanced performance for a variety of critical workloads. In addition, the HSE 3.0 engine is optimized for performance around workloads with monotonically increasing keys (such as time series data), multi-client workloads, the ability to store compressed and uncompressed values together, and other performance improvements.
Java language bindings are now available for the HSE 3.0 API, and Python bindings have been updated to accommodate these API changes.
HSE is a fast embedded key-value store designed for SSDs and persistent memory said Micron. HSE optimizes performance and endurance by coordinating data placement across DRAM and multiple classes of solid-state storage.
